Discussion
This study was conducted to model the relationships of academic identity, psychological sense of school membership, and teacher affective support with academic performance by the mediating role of academic adjustment. The results revealed that moratorium identity and achievement identity can significantly predict students' academic performance. These results are in line with those of studies performed by Chorba et al. (2012)
[24] and Gazidari et al. (2015)
[6]. Adolescence is the period of transition from childhood to independence and adolescent responsibilities. During this period, young people go through many changes moving into physical maturity. These various changes make adolescents face multiple problems in adapting themselves to society and acquiring a healthy identity [
25, 26].
Based on the result of the current study, the psychological sense of school membership can positively and significantly predict students' academic performance. The results of a study carried out by Peng et al. (2011) pointed out that the sense of school belonging can increase flexibility, self-esteem, and well-being in students, which in turn, can significantly improve students' academic performance
[27]. On the other hand, a poor sense of school belonging is associated with academic failure, behavioral disorders, substance use, truancy, delinquency, as well as dropping out of school
[28]. Adolescents who form strong social bonds with schools are more likely to engage in social behaviors, develop their educational potential, and are less prone to suffer from behavioral disorders than those who fail to build such bonds
[29].
The results of this study also indicated that the relationship between teacher affective support and students' academic performance was not significant. These results are consistent with those of studies conducted by Wentzel et al. (2010)
[30], Hughes and Kwok (2007)
[31], and Sharhani (2016)
[32]. Students’ perceptions of their teachers’ perceptions have long been regarded as an important dimension of the classroom atmosphere. Moreover, the findings of the present research revealed that academic adjustment can predict students' academic performance both positively and significantly. Perera et al. (2015)
[33] and Soleimanifar and Shabani (2013)
[34] found the same results in their studies. Academic adjustment reflects learners' ability in adapting to educational conditions and roles imposed by a school as a social entity. This type of adjustment includes school satisfaction, academic achievement, teacher interest, communication with other students, and school staff' views on school performance.
According to the findings of the present study, there is a significant indirect effect of moratorium identity, diffusion, and achievement identity on academic performance by the mediating role of academic adjustment. However, the indirect effect of foreclosure identity through mediating variables on academic performance was not significant. These results are compatible with the results of studies conducted by Chorba et al. (2012),
[24] Beaumont (2009),
[35], and Gazidari et al. (2016)
[6]. To elaborate, it can be said that examining the components of academic identity can reveal their association with academic adjustment and affective well-being, consequently with academic performance.
Adolescents with an informational identity style are involved in the process of active self-inquiry, including seeking out, processing, and evaluating self-relevant information. In this process, the student or adolescent develops a cognition, not superficial and transient, helping them to understand the school properly. The result of this would be an increase in their adaptation and psychological well-being ultimately leading to improved academic performance
[35]. In other words, acquiring the achievement identity enhances an individual’s well-being and adjustment which ultimately improves academic performance. On the other hand, adolescents with a normative identity style act in a normative manner, and are always keen to internalize the values of reference groups, such as a particular religious school
[24]. Regarding this, adolescents with a diffusion identity style avoid as much as possible being exposed to identity issues. Therefore, their behavior is regulated by situational and momentary factors, and they benefit less from cognitive strategies
[35].
Other results of the current study indicated that the indirect effect of the psychological sense of school membership on academic performance by the mediating role of academic adjustment is significant. These results are consistent with those found by Gray (2017)
[9] and Mirzabeigi et al. (2018)
[10]. The sense of belonging to a school is defined as feeling accepted as a member of school. Students with such feelings are more motivated to participate in academic activities and develop a sense of being influential in classroom activities. Therefore, the development of a sense of belonging to the school is important due to its association with positive and negative adaptation outcomes.
Finally, the results showed that the indirect effect of teacher affective support on academic performance by the mediating role of academic adjustment was significant. These results are in line with those of studies performed by Wentzel et al. (2010)
[29], and Sharhani (2016)
[31]. Perceptual characteristics of teacher support, such as appreciation, listening, and respect, are associated with high self-esteem and low depression level among high school students regardless of their gender
[35]. In general, it seems that teacher support can improve the student/school relationship, which can increase the students’ psychological/affective well-being, as well as improving their academic adjustment. Regarding this, the chances of improving academic performance will increase. It should be noted that there were some limitations in the implementation of this research, including the use of questionnaires, sample size, and the method of research (i.e., cross-sectional). Therefore, other measuring methods and instruments, such as interviewing with questionnaires, increasing the statistical population, and using longitudinal studies, should be used to properly explain the underlying reasons for the growth or decline of academic performance at different educational levels.
Conclusions
The results of this study showed that in addition to the teacher affective support, academic adjustment, psychological sense of school membership, and some aspects of academic identity had a significant effect on students' academic performance. Furthermore, the findings indicated that academic identity (except for foreclosure identity), psychological sense of school membership, and teacher affective support significantly influenced academic performance by the mediating role of academic adjustment.
